Hurricane Simon strengthened off Mexico's Pacific coast as warnings expanded along the shoreline. At 15:00 Coordinated Universal Time (UTC) on 9 October, the National Hurricane Center (NHC) recorded sustained winds of 155 km/h, a minimum central pressure of 973 mb and a centre at 16.0°N, 104.7°W. Simon was moving northwest at 6 km/h. A Hurricane Warning remained in effect from Punta San Telmo to Punta Mita; Mexico added a Hurricane Watch from Punta Mita to San Blas; and a Tropical Storm Watch remained in effect east of Punta San Telmo to Lazaro Cardenas. Simon was rapidly intensifying and was forecast to become a major hurricane during the evening and strengthen further on Saturday. Forecast rainfall of 8–15 inches, with isolated maximum totals of 25 inches in parts of Michoacan, Colima, Jalisco and Nayarit through Sunday, could cause life-threatening flooding and mudslides.
The Global Disaster Alert and Coordination System (GDACS) placed episode 6 on Orange alert, signalling medium potential humanitarian impact. About 50,000 people are within its latest forecast footprint of Category 1-or-stronger winds, and the episode summary lists a modelled overall cyclone-track maximum of 222 km/h, Category 4. These are forecast-model outputs, not confirmed counts of people affected, displaced, injured or killed. Earlier model snapshots remain dated history: episode 4 was Red with up to about 760,000 people in its impact timeline, episode 3 was Orange with about 90,000 people and episode 2 was Red with about 1.1 million people in their respective Category 1-or-stronger wind footprints.
Forecasts differ. In episode 6, the Hurricane Weather Research and Forecasting (HWRF) model showed 162 km/h winds, storm surge up to 2.1 m and rainfall up to 1,149 mm; the Global Forecast System model showed 151 km/h winds, storm surge up to 1.7 m and rainfall up to 625 mm; and the European Centre for Medium-Range Weather Forecasts model showed 162 km/h winds, storm surge up to 1.6 m and rainfall up to 449 mm. These remain separate dated model outputs. WorldsAid has not combined them or presented them as observed impacts. The cited sources report no confirmed casualty, displacement, affected-population, infrastructure-loss or procurement total, and none is inferred. NHC observations, warnings and forecasts remain separate from the modelled maximum-wind and exposure estimates.
